Abstract: PURPOSE:To relieve the surface roughing of the main surface of the emitter forming region of a bipolar transistor by applying an etching treatment to an insulating film on the main surface only once and improve the yield of a semiconductor integrated circuit device by a method wherein a gate material on the emitter forming region is removed after the gate electrode of a MIS-FET is formed. CONSTITUTION:A base lead electrode 33 is formed on the main surface around the emitter forming region of a bipolar transistor and an insulating film 23 and a gate material are successively formed over the whole surface of a substrate including the main surface of the channel forming region of a MIS-FET. Gate electrodes 36 and 37 are formed on the surface and, at the same time, the gate material 32 is left on the emitter forming region. Then the gate material 32 is removed by isotropic etching and the insulating film 23 of the foundation is removed to form an emitter lead electrode 34 on the main surface of the region. Therefore, the insulating film 23 is subjected only once to an etching treatment by which the gate material is removed and the damage of the main surface of the region can be relieved, so that the yield of a semiconductor integrated circuit device can be improved.

Abstract: PURPOSE:To easily peel a transmuted resist pattern by a method wherein a photoresist film and a water-soluble non-photosensitive thin film on a semiconductor substrate are patterned and a photoresist pattern into which ions are implanted selectively is lifted off together with the lower-layer water-soluble non-photosensitive thin film. CONSTITUTION:A water-soluble non-photosensitive thin film 2 with a film thickness of about 0.2 mum is formed as a first substratun on the whole surface of a semiconductor substrate 1; then, a positive-type photoresist film 3 is coated with a film thickness of about 1.5 mum. When this assembly is exposed to light in this state, the photoresist film 3 is divided into an exposed part 4 and unexposed parts 4'; when this film is developed, only the unexposed parts 4' are left and the photoresist film 3 is patterned. Then, when ions are implanted from the surface, ion-implanted regions 5 are formed on the surface of the semiconductor substrate 1. During this process, the photoresist film forming a resist pattern is transmuted by energy of the implanted ions and becomes difficult to peel however, if the film is immersed in pure water for sufficiently long hours, it can be lifted off simultaneously with dissolution of the lower-layer thin film 2.
